Table 3 a Description of data fields associated with each wild sampling event [all_wild_sample_events]. b Description of data fields associated with each wild fish that was assessed for sea louse infestation [all_wild_fish_lice].
Field | Description |
|---|---|
event_id | A unique ID associated with each wild sampling event |
sampledate | Date when the sampling event took place (dd/mm/yyyy) |
dfozone | One of seven fish health zone codes where the event took place. There were also a group of events collected by the Hakai Institute at various points along the Johnstone Straight. These do not fit neatly into a single existing sub-zone and so this field has been left blank for those events, while their ‘region’ (see next field) attribute has been noted as “BA/DI border”. |
region | One of fourteen areas along the BC coast. (Some DFO zones have only one region, e.g. {3.4} = {Port Hardy}, while others have several, e.g. {2.4} contains {Esperanza} {Espinosa} {Muchalet} {Quatsino}.) |
sample_site | A textual name that was used to describe the specific sampling site |
latitude | Latitude of sampling location in decimal degrees (to 4 decimal places) |
longitude | Longitude of sampling location in decimal degrees (to 4 decimal places) |
source | One of ten textual values representing the programme or organisation responsible for the sampling event. (See Table S1 for details relating to each of these programmes and their protocols.) |
source_code | A short-hand label by which to refer to the ‘sources’ noted above. |
protocol | One of three labels {Lethal} {Non-lethal} {Mixed} used to indicate the host capture and sea lice enumeration method adopted for a particular event. (See Table S1 for further detail.) |
Field | Description |
|---|---|
event_id | ID that associates each fish with the event in which it was sampled |
fish_id | A unique ID associated with each wild fish that was sampled |
length | The measured fork length for each fish (in mm) |
weight | The weight for each fish (in g) |
height | The height (vertical measurement from the bottom of the belly to the top of the back) for each fish (in mm) |
fish_species | One of eight fish species designation to which each fish was allocated |
lep_cop | Number of sea lice identified as L. salmonis species at copepodid stage |
lep_chal | Number of sea lice identified as L. salmonis species at chalimus stage |
lep_motile | Number of sea lice identified as L. salmonis species at motile stage |

cal_chal | Number of sea lice identified as Caligus species at chalimus stage |
cal_motile | Number of sea lice identified as Caligus species at motile stage |

unknown_cop | Number of sea lice at copepodid stage but not identified to species |
unknown_chal | Number of sea lice at chalimus stage but not identified to species |
unknown_motile | Number of sea lice at motile stage but not identified to species |
unknown_unknown | Number of sea lice at an unidentified stage and not identified to species |
